Resilient Flooring Terminology a Dictionary of Flooring Terms
Above-Grade: Pertaining to the location of a finished floor where the floor is not in contact with the ground and which provides at least 18 inches of well ventilated space.
Abrasion: Wearing, grinding, or rubbing away by friction.
Across Machine Direction: The direction perpendicular to which a product moves through the manufacturing process.
Asphalt Tile: An obsolete floor surfacing unit composed of asphalt or hydrocarbon resins, or both, crysotile asbestos fibers, mineral fillers, and pigments.
Adhesive: A substance that bonds the floor to the subfloor.
Adhered: (See Perimeter Adhered)
Aluminum Oxide: Added to the urethane finish for increased abrasion resistance of the wear layer.
Backing: Vinyl is constructed of several different layers: the wear layer, the printed or decorative layer, an inner core consisting of a foam and vinyl layer, and a backing. The type of backing determines how it can be installed.
Below-Grade: Pertaining to the location of a finished floor that is in direct contact with the ground or with less than 18 inches of well-ventilated space.

Resilient Flooring: An organic floor surfacing material made in sheet or tile form or formed in place as a seamless material of which the wearing surface is non-textile. The resilient floor covering classification by common usage includes, but is not limited to asphalt, cork, linoleum, rubber, vinyl, vinyl composition, and polymeric poured seamless floors. Resilient in this sense is used as a commonly accepted term, but does not necessarily define a physical property.

Rotogravure: The most commonly used method for making residential vinyl floors. This process involves a print cylinder that spins around while the vinyl’s core layer (called the gel coat) passes underneath. The cylinder systematically prints various colored ink dyes to create the pattern.
Rubber: Rubber flooring is extremely durable, virtually indestructible, quiet and warm to walk on. It also resists dents and stains and its waterproof surface has an anti-slip finish. However, rubber is relatively expensive and must be installed by an experienced installer for maximum performance.
Seams: Since vinyl comes in 6’ and 12’ widths, seaming may be necessary depending on the area to be covered. Certain patterns will hide seams better. For example, tile patterns with grout lines are better able to mask seams.
Seam Sealer: A thin liquid adhesive applied to the cut edges of carpet to lock in the tufts and prevent edge ravel. Seam sealers may be visible in contrast with different vinyl textures and finishes.
Sheet Resilient Flooring: Flexible resilient flooring, packaged in roll form, in which the length substantially exceeds the width.
Slip Resistance: The ability to counteract loss of traction.
Solid Vinyl Tile: A resilient tile flooring composed of binder, fillers and pigments compounded with suitable stabilizers and processing aids. The tile meets requirements of ASTM Specification F 1700. The binder consists of polymers and/or copolymers of vinyl chloride, other modifying resins, and plasticizers which comprise at least 34% by weight of the finished tile. The polymers and copolymers of vinyl chloride comprise at least 60% of the weight of the binder.
Static Coefficient of Friction: The ration of the tangential force that is needed to start uniform relative motion between two contacting surfaces to the perpendicular force holding them in contact.
Straight-Edge: Any strong, straight piece of metal that can be used for cutting straight lines for installing vinyl sheet and tile.
Subflooring: A rough floor on top of which the vinyl flooring is applied. That structural layer intended to provide support for design loadings which may receive resilient floor coverings directly if the surface is appropriate or indirectly via an underlayment if its surface is not suitable.
Substrate: The surface on which the vinyl flooring will be laid. If installing over a wood substrate, an underlayment will generally be necessary. A concrete substrate will not require an underlayment but will require some floor preparation.
Tangential Force: A force that acts on a moving body in the direction of a tangent to the curved path of the body.
Terrazzo: A form of mosaic flooring made by embedding marble, onyx, granite, or glass chips in Portland cement, polyacrylate modified Portland cement, or resinous matrices. The terrazzo is poured in place, cured, ground, and then polished. Rustic terrazzo is a variation where, in lieu of the grinding and polishing, the surface is washed with water otherwise treated to expose the chips. Quartz, quartzite, and river bed aggregate can also be used.
Texture: The term used to describe the surface look and feel of flooring. Textures can range from silky smooth to hand-scraped and distressed.
Tile: Resilient Flooring Resilient flooring which is packaged in flat pieces which can be installed as individual units.
Traction: The adhesive friction of a body on a surface on which it moves.
Transition Strips: Installation accessory that bridges two floors of different heights to equalize the height differential. Transition strips are functional and decorative.
Underlayment: A material placed under resilient flooring, or other finished flooring, to provide a suitable installation surface.
Ultraviolet Light: Ultraviolet(UV) light is part of the light spectrum. UV light wavelengths cannot be seen by the human eye.
Underlayment: Layer of material usually installed on or over a subfloor that provides a surface suitable to receive a new floor covering.
VCT Vinyl Composition: Tiles A resilient floor covering composed of binder, fillers, and pigments. The binder shall consist of one or more resins of poly (vinyl chloride), or vinyl chloride copolymers, or both, compounded with suitable plasticizers and stabilizers. Other polymeric resins may be incorporated as part of the binder.
Vinyl: Made from a mixture of polyvinyl chloride and plasticizer, it is usually flexible and non-porous. Pigments are added for color.
Vinyl No-Wax: A surface that protects that color and pattern of the floor, but needs floor polish to maintain a high gloss.
Vinyl Sheet Flooring: Resilient flooring, available in roll form, providing an installation with few seams.
Vinyl Tile: Resilient flooring available in flat pieces usually measuring 12” x 12” which can be installed as individual units.
VOC’s (Volatile Organic Compounds): VOC is an acronym for volatile organic compounds, which are gases that can trigger allergic reactions, asthma and upper respiratory infections.
Wear: The accumulative and integrative action of all the deleterious mechanical influences encountered in use which tend to impair a material’s serviceability. Such influences include, but are not limited to abrasion, scratching, gouging and scuffing.
Wear Layer: A layer of material applied to the top surface of vinyl flooring. The thickness of the wearlayer varies with each vinyl product collection, or series, and is generally measured in mils. The thickness of a mil is about the same as a page in a phone book. Premium wearlayers offer superior resistance to stains, scuffs and scratches. How long a vinyl floor will look new and fresh is based on the wearlayer’s performance.
